VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 237,688, dated February 15, 1881.

Application filed August 14, 1880.

all whom it may concern Be it known that I, FREnRIcK MAR UART, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a certain new and Improved Vapor-Burner; and I do hereby declare that the following is a full, clear, and complete description thereof.

This invention is an improvement in vaporburners.

Said improvement consists of an annular vaporizin g-chambersurroundin g the upper end of a tube which projects above the top of the chamber into a removable dome or cap. The lower end of said tube curves downward to a needle-valve arranged in a horizontal'relation to the end of the tube, and into which tube the gas-jet from the valve is received, and thereby conveyed to the dome or combustionchamber, above the generator or vaporizingchamber above alluded to. The generator is put in communication with an oil-reservoir by an induction-pipe, and with the needle-valve and its accessories by an eduction gas-pipe, which also serves as a gasgenerator conjointly with the main generator.

The oil-reservoir above alluded to-a relative part of the vapor-burner-consists of a cylindrical vessel provided with a dishing bottom having a central opening closed and opened by a screw-valve working in a nut-center or spider, all of which is more fully described and set forth in the following specification, reference being had to the accompanying drawings, making a part of the same, in which- Figure 1 shows a side elevation of the burner and reservoir. Fig. 2 is plan view with the dome removed, showing the top plate of the generator. Fig. 3 is a partial vertical section of the burner. Fig. 4 is an inside view of the bottom of the oil reservoir or can. Fig. 5 is a vertical central section of the bottom of the oil-can and part of the sides.

Like letters of reference refer to like parts in the several views.

As shown in the drawings, A represents the gas-generator, which consists of a tubular annular chamber, B, having a semicircular crosssection, Fig. 3, surrounding the gas-flue O, passing centrally up through the chamber into the dome or cap D of the burner. Said cap is removable, and is pierced by perforations a and 1), Fig.3. The cap is retained in place (No model.)

upon the generator by an annular flange, E, raised above the roof F of the generator, upon which roof the cap or dome stands, as shown in the drawings.

G is the oil-induction pipe, connecting the generator with the oil-can I-I through the intervention of a tube, I, and couplings.

J is an eduction gas-pipe, in open relation with the generator and needle-valve K, of which L is the screw-stem and M the valve seat or chamber. Said needle-valve and its fixtures are like those in common use.

N is an'oil-cup, the purpose of which will presently be shown.

The oil-reservoir H, above referred to, con sists of a cylindrical vessel, of which 0 is the bottom, dishing in shape, and provided with a central opening, P, Fig. 4, leading into a small funnel-like outlet, A, Fig. 5, of which B is a tubular stem whereby the oil-can is attached to the induction-pipe I. The bore of the stem B is closed by a valve, 0, Fig. 5, terminating the end of the rod D. Said rod is screwed into a threaded center piece or spider, Q, Figs. 4 and 5, and extends upward through the can to the outside, as seen in Fig. 1, and is operated thereat by a thumb-piece, It, for opening and closiu g the valve O alluded to.

The practical operation of the above-described vapor-burner is as follows: By opening the valve 0 oil flows from the can into the generator, filling it and the cduction-pipe J as far as the needle-valve. In order to light the burner, a small quantity of oil is filled into the cup N by opening the needle-valve, which oil, by pressure, is ejected therefrom into the mouth of the flue U, and runs therefrom into the cup. The oil in the cup is then fired, the heat of which being immediately about the needlevalve and the pipe J, the oil therein is vaporized, and is allowed to escape therefrom through the seat of the open valve. The issuing gas passes at once up the flue O to the burner or dome and issues from the perforations a and b in jets of flame. The heat resulting from the flame-jets heats the generator, and .the oil therein is quickly vaporized and passes therefrom to the needle-valve, from which it issues and ascends the flue O to the dome or burner, wherein it is consumed for domestic use, and for generating gas for supplying the burner.

The purpose of the valve 0 is to prevent too much oil from flowing into the generator from the can, and to regulate the pressure thereof. Valve 0 can be opened more or less, as the quantity of oil may be required to feed the burner, and at the same time to control the pressure by regulating the quantity of oil for use.

For the increment of heat at the underside ofthe generator perforations d, Fig. 2,are made in the top of the generator, immediately around the flue, between said flue and the side of the generator, as seen at d in Fig. 3. Jets of flame issue from the perforations and heat the under side of the generator, thereby facilitating the "aporizing of the oil. The oil is filled into the can H through an opening in the top covered by a cap, m.

To prevent an overflow of oil is the purpose of the safety-cock n, Fig. 1, which, on filling the can to the cock, will flow therefrom, showing that the can is full enough for practical use. The cock is then closed. By this means overflowing and flooding the can with oil are avoided.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In vapor-burners, the annular tubular generator surrounding the flue G, in combination with the perforated top plate and flue C, substantially as and for the purpose described.

2. The combination of the annular tubular generator A, flue G, perforations d d, and induction and eduction pipes G, J, and I.

3. The combination of the annular tubular generator surrounding the flue G, perforations d d, induction and eduotion pipes G, J, and I, and needle-valve, and perforated dome D, substantially as and for the purpose described.

In testimony whereof I afflx my signature in presence of two witnesses.
